A new study of early-stage Alzheimer’s disease reports that sedentary patients show significant deterioration in MMSE total score compared to more active patients, and that walking on a regular basis appears to stabilize cognitive decline (Winchester et al. Arch Gerontol Geriatr 2013;56:96-103). A total of 104 AD patients were followed over a 12-month period and categorized as Active or Sedentary based on Yale Physical Activity Survey scores.
